Cities and governments worldwide have stepped up large-scale tree plantation initiatives as part of broader efforts to combat rising urban temperatures and mitigate the heat island effect intensified by climate change. In the United States, Phoenix has launched a major Urban Forest Initiative backed by $5 million in funding to increase shade coverage in heat-vulnerable neighbourhoods, create green jobs, and plant tens of thousands of trees over the coming years to cool city streets and public spaces. planetizen.com
